That doesn't mean it's not worth a try...

Please enable the serial.log, reproduce the issue and then share both the systeminfo bundle and the gcode file you have this issue with so we can compare.

Were your able to reproduce it while serial logging was enabled?
I don't see anything in the logs
the last height changing command was

2023-05-27 09:14:14,656 - Send: N32 G1 Z-2.7 F7800*12

and the last location report from the printer was 111ms before you paused the print

2023-05-27 09:15:19,756 - Recv: X:290.40 Y:157.33 Z:-2.70 E:41.76 Count X:23232 Y:12586 Z:-1557

The printer thought it's still at the same height.
